The main control unit 200 can transmit a predetermined number of display control commands at a predetermined timing to the special symbol display device 100, and the special symbol display device 100 receives the command. Based on the command, the CPU in itself performs detailed display control without depending on the main control unit 200. Furthermore, a communication mode by one-way communication in which only a command is transmitted from the main control unit 200 to the special symbol display device 100 is adopted.

A power supply circuit 212 for supplying power and a reset circuit 213 for outputting a reset signal at predetermined time intervals are connected to the main control unit 200. A pulse signal generated by the periodic timer counter is input from the control unit 200, and a monitor signal for monitoring the current supply state from the power supply circuit 212 is input.

These commands are always required no matter how the variation mode of the variable display changes in accordance with the game situation, and the main control unit 200 determines when the game situation is such that the symbol variation display is started. These five commands are transmitted to the special symbol display device 100 at a predetermined timing in one variable display control.

Therefore, since the special symbol display device 100 is responsible for fine display control such as the change of the symbol display speed, the program for the main control unit 200 is simplified, and the program is changed even if the display content is changed. The main control unit 200 can execute a command defining a time from the start of the variable display of the symbol to the stop thereof, and a command for designating the symbol. , The program is further simplified.

FIG. 5 is a timing chart showing the command transmission / reception timing. As previously mentioned,
The command consists of a 1-byte mode (MODE) and a 1-byte event (EVENT).
In this example, the main control unit 200 transmits mode (MODE) information at the first rising edge of the strobe signal (DUSTB) generated by itself at the time of a command change, and then transmits the two strobe signals (DUSTB). Event (EVENT) information is transmitted with the rise of the eyes. Then, in response to this, the CPU 1020 of the special symbol display device generates an interrupt when a strobe signal (DUSTB) is transmitted, receives a command by this interrupt processing, and stores the command in the RAM 1090.

Next, first, a normal control operation performed by the main control unit 200 or the CPU 1020 of the special symbol display device 100 will be described with reference to FIG. 10 (a general flowchart of game control) and FIG.
, And thereafter, features of the present invention will be described to facilitate understanding of the present invention.

In step S180, data necessary for display control of the ordinary symbol display device 107 is stored in the RAM.
203 and a command necessary for display control of the special symbol display device 100 (see FIGS. 6 to 9).
(Including the commands described in the above) are stored in a predetermined area of the RAM 203, and the timer values of the various timers are reduced (step S190). In step S180, the main control unit 200 determines a command of a necessary mode and event according to the game control with reference to the command data table area 202, and stores digital information indicating the determined mode and event in the RAM 203 in a predetermined manner. Store in area.

Next, in step S195, the starting port operating solenoid 300 and the special winning port operating solenoid 302 are driven to control the opening and closing of the special winning opening 106 and the opening / closing member 120 of the special symbol starting opening 104 in a predetermined pattern. Then, in step S220, a prize ball setting process for outputting control information for causing a prize ball payout device (not shown) to perform a payout operation is executed. Further, in steps S230, 240, and 250, a game (not shown) External information processing for outputting various game data to the machine management device, a display lamp control process for storing a command for lighting control of the lamp display devices 110 and 112 in accordance with a game state in a predetermined area of the RAM 203, sound effect generation Device 11

Next, in step S260, R
The data stored in the AM 203 is output to the corresponding device via the output port 215 (port output process), and the device that receives the data performs a control operation based on the data. Then, a strobe signal is first output to the special symbol display device 100, and the mode and event data stored in the RAM 203 in step S180 are transmitted as shown in FIG. Thus, the commands shown in FIGS. 6 to 9 are transmitted from the main control unit 200 to the special symbol display device 100 and received.

In step S270, the reset circuit 21
The reset standby process is executed until the reset signal is input from Step 3, and when the reset signal is input, the process shifts to Step S110 to continue the gaming machine control. Note that the reset standby process includes updating of the various random number generation counters described above.

Next, the operation of the CPU 1020 of the special symbol display device 100 receiving the command will be described with reference to FIG. First, in step S1100, the CPU 1020 sets its own stack pointer,
Initialization of the RAM 1090, initialization of the RAM 1090 itself, and the like are performed, and in step S1102, it is determined whether a new command has been input. When it is determined that a new command for display control has been input, (Y

In step S1104, in the interrupt processing described with reference to FIG.
Copies the received command to the RAM 1090, and checks whether the command is normal or not. Next, CPU1
020 determines the start address of a processing table (not shown) in order to obtain a necessary command for performing fine display control independently of the main control unit 200. Then, in step S1108, the image processing LSI 1060 The data in the necessary area of the RAM 1090 is updated in order to output the data to the RAM 1090.

Next, in step S1110, RA

The developed image data is temporarily stored in the video RAM 1080 and then sent to the LCD panel interface circuit 1100 to be sent to the LCD panel 1120. Is displayed. Then, in step S1122, a test signal as described later is output. In this way, at the set display position in the special symbol display device 100, the symbol variation display at the set speed, the display of the background image, and the like are performed, and the test signal is also output.

FIG. 13 and FIG. 14 are explanatory diagrams of an example of a transmission timing of a command transmitted from the main control unit 200 to the special symbol display device 100, and the transmission command. When a predetermined condition such as a game ball winning in the special symbol starting port 104 is satisfied, the unit 200 first transmits a command for designating a symbol change and specifying a time from the start of the symbol change to the stop of the symbol change. (), A command for designating a left stop symbol is transmitted after a lapse of T1 time (), and a command for designating a middle stop symbol is transmitted after a lapse of T2 time (), and right after a lapse of T3 time A command for designating a stop symbol is transmitted (), and a command () for stopping all symbols is transmitted after a lapse of T time from the start of fluctuation, and further, these Before receiving the command, the CPU 1020 of the special symbol display device 100 performs a series of variable display control by performing fine display control such as a change in the change speed before the time specified by elapses. After the elapse, the variable display control ends.

Next, an embodiment of a main part of the present invention will be described. FIG. 16 is a block diagram of the special symbol display device 101 according to the embodiment of the present invention. As can be seen by comparing with the special symbol display device 100 shown in FIG. 3, the special symbol display device 101 of this embodiment has an output port 1200 for outputting a test signal to an external tester and a P port.
The substrate 410 on which the LD 500 is mounted and the substrate 400 on which other device groups are mounted are divided between the CPU 1020 and the output port 1200 which are test signal output devices for outputting test signals in the device group. Is provided with a PLD 500 for performing signal processing for outputting a test signal.

The PLD 500 and the output port 1200
And other device groups may be provided on the same substrate. In this case, the PLD 500, the output port 1200,
In order to be functionally separated from other devices,
It is desirable to arrange the PLD 500 and the output port 1200 collectively. Further, the substrate 410 on which the PLD 500 and the output port 1200 are mounted may be provided outside the special symbol display device 101.

The device group includes a CPU 1020, a program ROM 1040, an image processing LSI 1060,
Video RAM 1080, RAM 1090, LCD panel interface circuit 1100, LCD panel 112
0, a data receiving circuit 1140 and a power supply circuit 1160,
A character ROM 1180 is mounted on the board 400.

As shown in FIG. 17, an interface section 502 is formed on the PLD 500. The interface unit 502 is provided by the CPU 1020 by the test signal inspection device 2.
When a test signal is output to the output port 1200, a signal is supplied to the output port 1200 with a signal specification suitable for the model.
It functions as an interface that mediates transmission and reception of signals between the 020 and the test signal tester 2000 side.

The signal shaping section 504 formed in the PLD 500 performs shaping processing such as comparing various signals at a predetermined level as shown in FIG. 15 to obtain an accurate binary signal. Therefore, an accurate test can be performed by the shaping process of the signal shaping unit 504.

FIG. 18 shows how the port specifications change when the model is changed. Generally, when the model is changed, the signal specifications are different even for the same port number. Therefore, when the test signal specification is changed in accordance with the model change, the change is completed only by changing the interface unit 502 of the PLD 500.

Moreover, this PLD (programmable logic device) is attached to a dedicated writer connected to a computer activated by the OS, and if input / output signals are defined on a computer screen so as to perform desired signal processing. Since the gate is automatically formed inside, the number of man-hours for change is extremely small. Further, a program for setting a gate may be stored in the program ROM 1040. Therefore, by using the PLD 500, the number of steps for outputting a test signal can be further reduced.

Therefore, according to the embodiment of the present invention,
Since the PLD 500 that performs signal processing for outputting a test signal is provided between the CPU 1020 as a test signal output device and the output port 1200, the processing contents of the interface unit 502 of the PLD 500 can be changed for each model. It can easily correspond to different test signal output specifications.

The signal shaping section 504 is formed in the PLD 500, and the CPU 1020 serving as a test signal output device is formed.
If the test signal is supplied to the output port 1200 after being shaped, an accurate test can be performed. If the interface section 502 and the signal shaping section 504 are formed by a PLD (programmable logic device) 500, it is possible to easily cope with a change in test signal specification for each model.

When the device group and the output port 1200 are mounted on separate boards 410 and 400, respectively, the device group necessary for commercialization can be obtained by removing only the board 410 on the output port 1200 side. Only substrate 4
10 can be left on.

In this embodiment, a special symbol display device has been described as an example of a peripheral device. However, the present invention can be similarly applied to other peripheral devices. Various modifications and changes can be made without departing from the spirit of the present invention.
Having a function other than the signal shaping unit 504, mounting the PLD 500 on the substrate 400 side,
Various modifications and changes, such as providing D500 without mounting on both substrates 400 and 410, are mentioned.

In the above description, a pachinko machine has been described as an example of a game machine, but the present invention is applicable not only to pachislot machines and video game machines, but also to other game machines. Needless to say.

As described above, according to the present invention, the signal processing means for performing signal processing for outputting the test signal is interposed between the test signal output device and the output port. Just change the processing content of the processing means,
The effect is obtained that it is possible to easily cope with test signal output specifications that differ for each model.
